Discussion:As may be seen from the above distribution, this South American species has a very extensive range covering subandean Venezuela, Colombia and Peru; the basin of the upper and middle Rio Orinoco in Venezuela and the western part of the Amazon basin.
This species is one of the six which are found on the Pacific coast of Colombia, the other being the South-American S. Mitscherlichii (Valle del Cauca and Choco), and S. colombiensis (Valle del Cauca), also S. Peckii (Valle del Cauca), S. darienensis (Valle del Cauca), and S. panamensis (Antioquia) which are found in Central as well as in South America. S. panurensis doubtless occurs also in subandean Ecuador and Bolivia. It is very likely that this species is not found in the three Guianas, also in the State of Para and in the Territory of Amapa in Amazonian Brazil.
For information on the position of this species in Ducke’s key made on the basis of fruit characters, see under S. rondeletioides.
For the record of the use of this species in curare in Venezuela (Puerto-Perico, et tout le long du Raudal d’Atures) (Gaillard 16) see (5: 13).
